A system for sensing and responding to detected activity or an event in a region is provided. The system may comprise: a modular edge computing platform configured to provide a predetermined functionality for a particular application, the modular edge computing platform is configured to process sensor data to generate processed data, and transmit the processed data; and a remote entity that comprises (i) a cloud analytic configured to receive the processed data from the modular edge computing platform and analyze the processed data, and (ii) a cloud user interface module configured to provide a graphical user interface on a user device, the graphical user interface displays one or more results generated by the cloud analytic upon analyzing the processed data.

A luminaire has a first housing portion and a second housing portion formed of a polymeric material. A hinge pivotably connects the first housing portion to the second housing portion and includes a pintle formed as one-piece with one of the first and second housing portions and a knuckle formed as one-piece with the other one of the first and second housing portions. A sealing structure seals a compartment formed between the first housing portion and the second housing portion. The sealing structure includes a channel supported by one of the first and second housing portions and a frame supported in the channel. The frame supports a deformable gasket. A sealing member extends from the other one of the first and second housing portions where the sealing member extends into the channel and engages the gasket. A locking feature secures the first housing portion to the second housing portion.

Systems, devices, and methods are disclosed in which one or more light sources, a detector, a processor and a controller are configured such that light from the one or more light sources improves the ability of a human or automated motor vehicle driver to identify and avoid pedestrians. The one or more light sources may provide spot illumination to moving objects or pedestrians on a road surface, with the spot illumination following the moving object or pedestrians along the portion of the road surface. The one or more light sources may project images on the ground or on other surfaces. The light source may be carried by a pedestrian or on personal transport used by a pedestrian. The light sources may be stationary and provide lighting for a pedestrian street crossing.

The present invention provides a luminaire (1), in particular a street lamp. The luminaire comprises at least one lighting means (5), such as at least one light emitting diode, at least one sensor unit (15) including an acoustic sensor (2) configured to measure environmental sound, and further comprising a processing unit (3). The processing unit (3) is configured to identify an environmental situation of the luminaire (1), in particular the street condition at the street lamp, on the basis of at least one characteristic of the measured environmental sound, such as the amplitude, frequency or pattern of the measured environmental sound and/or control information for controlling light emission.

A light emitting device (3) comprising an array of light emitting diodes (LEDs) (301-317), said array of LEDs comprising a plurality of LEDs (61-69), a center (31), an perimeter (32) and a first axis (X) extending through the center and transverse to the outer circumferential edge, where each LED of the array of LEDs comprises a size and a shape, where the plurality of LEDs is arranged on a plurality of lines (L) extending in a direction 5 from a point on the first axis (X) towards the outer circumferential edge (32), two or more LEDs of the plurality of LEDs being arranged on each line, and where the two or more LEDs on each line are arranged such that at least one gradient in the size of the LEDs and/or the shape of the LEDs is provided in a direction along said line.

A street light allows an electronic device installed therein to work properly. The street light has an internal chimney structure for dissipating heat from the electronic device and preventing any liquid from flowing into a space where the electronic device is accommodated. This allows the street light to internally provide both a dry environment and a heat dissipation mechanism for the electronic device, without closing an internal space of the street light, so as to greatly improve the above undesirable structural drawbacks of the conventional street light.

A base unit (1), e.g. a luminaire, comprises fixation means (3, 5, 15) configured to fixate a module (11), e.g. a light module, in the base unit. The fixation means, e.g. comprising one or more protrusions (15), one or more recesses (3) and one or more magnetic field generators (5), is configured to release the module from the base unit upon detecting an unmanned aircraft (31) being docked with the base unit or the module.

Example embodiments relate to luminaire head assemblies with brackets. One example luminaire head assembly includes a housing provided with a socket assembly. The luminaire head assembly also includes a light source arranged in the housing. Additionally, the luminaire head assembly includes a bracket releasably attached to the housing. The bracket is configured to fix the housing to a pole. The bracket has a first end for connection to a pole or pole connector and a second end attached to the housing. The bracket is provided with a through-hole at the second end. The socket assembly extends at least partially in the through-hole.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
